Whoa, super cool work! I can see Coprocessorjs being really useful.

I love seeing modern dev for 68k Macs. The toolbox can be a pain at first, but it's not so bad once you internalize all the different managers you have to remember. MacApp supposedly helps do a lot of the work for you, but I haven't gotten around to doing much with it yet—it's more fun implementing my own abstractions like an async task manager.
